Hybrid Precoding for Millimeter Wave RoF Systems [PDF]

2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020
<div>Large propagation path loss and limited scattering</div><div>of millimeter wave (mm-wave) channels create new challenges for physical layer signal processing. Hence, in this paper, we propose a photonic hybrid precoding model for mm-wave radio-over-fiber systems that overcomes hardware constraints on radio frequency precoding ...

Optomagnonically induced RoF chaotic synchronization

New Journal of Physics, 2022
Abstract Optomagnonics is a good platform for the interplay of radio frequency and optical signals, which are the primary communication carriers in the present day. On the basis of optomagnonics, we provide a multi-scale method for analyzing its behavior, including frequency comb and RoF chaotic synchronization at the microwave scale ...
